Definitions

  • the invention is based on a filter cover device in modular design according to the type specified in the preamble of claim 1.
  • Such generic filter cover devices in modular design are already known, for example from DE-AS 20 36 230, DE-OS 22 11 838.
  • the housing module on the mounting surface of which the liquid filter is mounted, is designed as a cuboid base body. Two opposite end faces of the cuboid base body are suitable for flanging additional auxiliary modules, so that different functions can be put together in a modular manner.
  • the inlet and the outlet are now in a common flange surface that runs parallel to the longitudinal axis of the liquid filter.
  • An auxiliary module with the additional function is attached to the other flange surface.
  • a modular preparation device for compressed air in which the individual function groups are modular, can be strung together as desired and can be pressed together by means of semi-conical areas.
  • the individual modules are designed as cube-shaped basic bodies that are chained together in a longitudinal direction, while the devices required for the additional functions are arranged in directions running transversely to them.
  • This design also leads to an expensive and complex solution which, above all, requires a large amount of space and is therefore unsuitable for many applications.
  • the filter cover device according to the invention in modular design with the characterizing features of the main claim has the advantage that it enables a relatively simple and inexpensive construction that can meet high demands on flexibility due to its extremely compact shape.
  • the various modules can be arranged coaxially to the longitudinal axis of the liquid filter, which favors a space-saving design and opens up a wide range of possible uses.
  • the individual modules can be easily assembled.
  • various functions can be implemented individually or in any combination, in particular the functions of hand pump and heater can be combined. It is particularly advantageous if the fastening means for fastening the filter cover device in the vehicle are arranged on the housing module and if the various auxiliary modules are designed for the functions end cover, hand pump, fuel return and heating.
  • FIG. 1 shows a first exemplary embodiment of a filter cover device in a modular design and with an attached liquid filter in a simplified representation and partly in section
  • FIG. 2 shows a top view of the filter cover device according to FIG. 1
  • FIG. 3 shows in detail the snap connection between the two module components
  • FIGS each shows a longitudinal section through various auxiliary modules in a simplified representation
  • FIG. 4 showing a cover plate as the first auxiliary module
  • FIG. 5 showing a hand pump as the second auxiliary module
  • FIG. 6 showing a fuel return as the third auxiliary module
  • FIG. 7 showing a fourth auxiliary module as an electrical heater
  • FIGS. 8, 9 and 10 show sealing means for sealing between the module components
  • FIGS. 11 and 12 each show a longitudinal section through a second or third filter cover device in a modular design in a simplified representation.
  • FIG. 1 shows a first section of a filter cover device 10 in modular design, to which a liquid filter 11 is attached.
  • the filter cover device 10 consists essentially of a housing module 12 and a first auxiliary module 13 mounted thereon, which is designed as an end cover.
  • the housing module 12 has for mounting the liquid filter 11 on its underside a mounting surface 14, in which a pair of first openings 15, 16 are arranged for fluid connection of the filter, which are sealed against each other in a manner known per se.
  • the liquid filter 11 can be designed here as a screw-on easy-change filter or as a filter housing with an exchangeable filter insert.
  • the housing module 12 essentially has the basic shape of an annular disk 17, the diameter of which is a multiple of its axial thickness. On the outer periphery of this washer 17 four connecting pieces 18, 19, 21 and 22 are formed, all of which lie in the same radial plane. As shown in FIG. 1 in connection with FIG. 2, in which the filter cover device 10 is shown as a top view, the connecting pieces 19 and 21 are unused blind connecting pieces, while the connecting piece 18 serves as an inlet and the connecting piece 22 as an outlet.
  • the housing module 12 has an attachment surface 23 on its end face lying opposite the mounting surface 14, on which the auxiliary module 13 is tightly and firmly attached.
  • a cylindrical and centrally located receiving bore 24 is provided in the mounting surface 23, which has a flat base surface 25.
  • This receiving bore 24 forms in the housing module 12 a socket connection 26 into which the auxiliary module 13 can be inserted with a plug connection 27.
  • the socket connection 26 on the housing module 12 and the plug connection 27 on the auxiliary module 13 together result in a plug connection 28, which facilitates the modular design.
  • a pair of second openings 29, 31 are formed in the area of the socket connection 26, which open into the base area 25 and which are spaced apart from one another.
  • the upstream second opening 29 communicates with the inlet 18, while the downstream second opening 31 with the dirt-side opening 16 in the mounting surface 14 is connected.
  • the first opening 15 located on the clean side, which lies in the area of the fastening with the aid of the centrally located hollow screw, is connected to the outlet 22.
  • the auxiliary module 13 designed as an end cover has a cylindrical base 32 to form the plug connection 27, on the outside of which an annular circumferential lip 33 is formed. With the auxiliary module 13 installed, the lip 33 engages in an annular groove 34 which is machined into the wall of the receiving bore 24. In this way, both modules 12 and 13 get caught when they are inserted into one another with their socket connection 26 and plug connection 27.
  • FIG. 3 which as a detail shows this plug connection 28 on an enlarged scale.
  • a transverse channel 35 which is open towards the end, runs in the cylindrical base 32 and fluidically connects the two second openings 29 and 31 to one another when the auxiliary module 13 is installed in the housing module 12.
  • a flat seal 36 is installed between the housing module 12 and the auxiliary module 13 in order to ensure reliable separation of the inlet and outlet side.
  • a flange 37 with elongated holes is formed on the housing module 12, with which the filter cover device 10 together with the liquid filter 11 can be attached to a machine component (not shown) or in the vehicle.
  • the connecting pieces for inlet 18 and outlet 22 are designed as threaded holes so that the fuel lines can be connected in the vehicle.
  • the assembly of the filter cover device 10 is very simple due to the modular construction. After inserting a flat gasket 36 into the socket connection 26 on the housing module 12, the auxiliary module 13 designed as an end cover is clipped in with its plug connection 27 and in the process arranged in a sandwich-like manner over the housing module 12.
  • the pressure medium to be cleaned flows to the housing module 12 at the inlet 18. It then flows through the upstream second opening 29 into the auxiliary module 13 and flows via the transverse channel 35 in the end cover 13 to the downstream second opening 31 of the main module 12.
  • the pressure medium flows from the second opening 31 essentially in the axial direction of the first opening 16 on the dirt side and from there reaches the interior of the liquid filter 11 via openings (not shown).
  • the pressure medium cleaned in the liquid filter 11 flows on the clean side through the first opening 15 into the housing module 12 and is conducted there to the outlet 22.
  • the end cover 13 thus only assumes a deflecting function for the pressure medium flowing through the filter cover device 10.
  • the first auxiliary module 13 which is designed as an end cover, is shown on its own in a longitudinal section, with its plug connection 27 with the molded lip 33 being clearly visible, as is the transverse channel 35 running in it.
  • FIG. 5 shows a simplified representation of a longitudinal section through a second auxiliary module 40, which is designed here as a hand pump.
  • the basic structure and function of such hand pumps are known per se, for example from DE-33 27 437 C2, so that they are not dealt with in more detail.
  • the hand pump module 40 like the first auxiliary module 13, has the same plug connection 27 with the associated lip 33, so that it e.g. can be clipped into the housing module 12 instead of the end cover 13.
  • FIG. 6 shows a longitudinal section through a third auxiliary module 41, which is designed here as a fuel return in a greatly simplified and schematic form.
  • a third auxiliary module 41 which is designed here as a fuel return in a greatly simplified and schematic form.
  • Such fuel returns in which the overflow quantity coming from an injection pump is returned to the filter or to the tank depending on the temperature, are known per se, for example from DE 34 22 979 A1, so that they are not dealt with in any more detail.
  • the third auxiliary module 41 like the other auxiliary modules 13 and 40, has a plug connector 27 of the same size, which is also provided with an annular circumferential lip 33.
  • a socket connection 26 is formed in the third auxiliary module 41 designed as a fuel return, into which each connector connection 27 of an auxiliary module can be clipped.
  • an oblique bore 44 runs through which pressure medium coming from the fuel return is guided in the direction of the dirt side of the liquid filter 11.
  • the other bore 42 is arranged so that it has connection with the second opening 29.
  • the third auxiliary module 41 thus represents a component that can be sandwiched between two other module components.
  • FIG. 7 shows a longitudinal section through a fourth auxiliary module 46, which is designed in a greatly simplified form as an electrical heater.
  • the fourth auxiliary module 46 like the third auxiliary module 41, has a plug connection 27 and an opposite socket connection 26.
  • the heating module 46 has bores 42 and 43, the bore 43 expanding into a chamber 47 in which an electrical heating element 48 is arranged.
  • the fourth auxiliary module 46 like the third auxiliary module 41, can be used as an intermediate module.
  • FIG. 8 shows a longitudinal section through the flat seal 36, as is used in the plug connection 28.
  • the openings 49 assigned to the second openings 29, 31 in the housing module 12 can be seen more clearly.
  • a circumferential bead 51 is arranged around the bores 42 and 43 or the corresponding channels in the auxiliary modules 13, 40, 41, 46, as shown in detail on an enlarged scale is shown.
  • FIG. 10 shows a longitudinal section through a rubber seal 52, as can be used instead of the flat seal 36 according to FIG. 8, in which case the bead 51 fixed to the housing on the auxiliary modules can then be omitted.
  • the rubber seal 52 enables a greater spring travel between the module components and enables a completely flat end face at the plug connection 27.
  • FIG. 11 shows a longitudinal section through a second filter cover device 60, which differs from the first filter cover device 10 according to FIG. 1 as follows, the same reference numerals being used for the same components.
  • the fourth auxiliary module 46 which is designed as a heater, is installed between the housing module 12 and the first auxiliary module 13. Due to the modular design, it is compact and the function of the electric heater can be integrated into the lid device in a more cost-effective and simple form.
  • FIG. 12 shows a third filter cover device 61, which differs from the second (60) according to FIG. 11 only in that, instead of the first auxiliary module 13 designed as an end cover, the second auxiliary module 40 designed as a hand pump is clipped into the heating module 46. In this way, the two functions of electric heating and hand pump can be combined in the filter cover device 61.
  • the housing module 12 can also be designed such that it has only two connecting pieces, which are in particular coaxial to one another. It may also be expedient to change the rotational position of the second openings 29, 31 in the housing module and the associated openings or channels in the auxiliary modules.
